Mono Monday : Rock

 Or, to be more accurate, rocks.
Crawley Peoples' Monument seems to be the nearest source of rock to me, so here's a part of it.
It sits in the town centre, commemorating the Queen's visit in 2006 to mark sixty years since the new town was founded.
The part I like best is the low, shiny black wall surrounding it, so handy for sitting on while sorting out your shopping.
